Abstract
To be able to produce an SCR catalyst (), in particular one having a zeolite fraction (Z) as catalytically active fraction, in a reliable process and at the same time achieve good catalytic activity of the catalyst (), an inorganic binder fraction (B) which is catalytically inactive in the starting state and has been treated to develop catalytic activity is mixed into a catalyst composition (). The inorganic binder component for the binder fraction (B) is, in the starting state, preferably porous particles (), in particular diatomaceous earth, which display mesoporosity. To effect catalytic activation, the individual particles () are either coated with a catalytically active layer () or transformed into a catalytically active zeolite () with maintenance of the mesoporosity.
